I have a JGS 50mm I'm going to run.

I was running an S362/S475 combo at the time with 5x14 injectors.

After that I ran an H1c with a 12cm HX35 housing, same injectors. Drilled out its divider and hogged it out to 1/8" smaller than the WG flapper, and even that was able to control boost levels. I was never able to get it to creep higher than what I set it at.

The guy who is helping me reach my goal (very well know puller engine builder) told me the 50mm will be a tad big but if I choose to get crazy later down the road with funny gas or what ever it will allow me to grow.

FWIW, I've only seen up to 44mm gates on daily drivers.

My plans are steedspeed t3 external wastegate, HX35W (from a 24v manual), a synapse 50mm wastegate, 12cm Hx35 non-wg housing and some bigger injectors. Later I have a Billet D12 Hx52 to make my twins with.

35/52 compounds? It would be super quick spool but not much air I think?

I ran a 52 as a single with a VE and it was able to light it. Don't get me wrong it was a pig low but came on in the 1,800ish rpm range.

Hx52 is either a 67 or 71mm inducer, depending on which one he has. As far as I'm concerned a 67mm turbo is able to provide more thN enough air to max out a VE's HP numbers. Trick is getting it lit fast enough to do it.

The exhaust housing on the 52's are pretty tight too. May end up being restrictive enough to slow down the 35's spool. If I think right the hx55's turbine housings interchange, so it shouldn't be too hard to open that up some.

My HX52 is tge 67mm unit I believe it's a 67/85/16cm will require large wastegate on hot pipe to keep boost from spiking, but I already understand that. Running both turbos at ~2.2 bar will flow enough for 450hp and should have no problem spooling by 1800. Goal is loads of Torque.

Wow that's a bigger turbine wheel than the s467 fmw I've got coming for my 4th gen. It's a 67.7/83/.9 t4. I'm going to mount it on a t4 steed speed that has the flange straight out (and it just shipped today!!) I didn't get the wastegate flange because I don't need one yet

I was off relooked it looks to be a 77mm so a 67/77/16 and is rated to over 1200 cfm and stable to over 60 PSI on it's own. As a compound it won't even be pushed to it's limits and the VE will have trouble fueling it to full power. I'd be happy with 500hp really goal is only to hit 1000wtq.

If you can get it lit fast enough 1000lb-ft of torque should be relatively easy with a ve
